Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring
gonadotropin-releasing hormone (GnRH). The analog possesses greater potency
than the natural hormone. The chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-leucyl-L-leucylL-arginyl-N-ethyl-L-prolinamide
acetate (salt) with the following structural formula:

Suspension INDOCIN for oral use contains 25 mg of indomethacin
per 5 mL, alcohol 1%, and sorbic acid 0.1% added as a preservative and the following
inactive ingredients: antifoam AF emulsion, flavors, purified water, sodium hydroxide or hydrochloric acid to adjust pH, sorbitol solution, and tragacanth.
Indomethacin is a non-steroidal anti-inflammatory indole derivative designated
chemically as 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic
acid. Indomethacin is practically insoluble in water and sparingly soluble in
alcohol. It has a pKa of 4.5 and is stable in neutral or slightly acidic media
and decomposes in strong alkali. The suspension has a pH of 4.0-5.0. The structural
formula is:

Taclonex Scalp® (calcipotriene and betamethasone dipropionate topical suspension) Topical Suspension contains calcipotriene hydrate and betamethasone dipropionate. It is intended for topical use on the scalp.
